Problems solved by technology

[0004] However, when using the above method to process synchronization tasks, the number of synchronization threads in the system corresponds to the number of master-slave relationships one by one. When the number of master-slave relationships in the system is large, the number of threads in the system will expand, thereby increasing the number of system overhead, affecting system performance; and, the synchronization thread corresponding to each master-slave relationship is usually idle, causing waste of system resources

Abstract

The invention discloses a synchronization task processing method and device based on time slice scheduling. The method includes the steps that a synchronization task is generated according to at leastone synchronization request sent by a slave node; the synchronization task is placed in a task queue; any idle thread in a thread pool acquires the synchronization task from the task queue and executes the synchronization task; whether or not the execution time of the synchronization task reaches the time specified by a preset time slice is determined, and if yes, the synchronization task is reset into the task queue. By adopting the scheme, the number of threads can be decoupled from the number of master-slave relationships, and a large amount of master-slave synchronization work in a systemcan be completed by the threads the number of which is lower than the number of master-slave synchronization relationships in the system, so that the system overhead is significantly reduced, and system resources are saved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for processing synchronous tasks based on time slice scheduling. Background technique [0002] The distributed system of the master-slave structure has become a commonly used database structure because of its high flexibility, high data reliability, low service node load, high data read and write efficiency, and the ability to achieve read and write separation. . [0003] In a distributed system with a master-slave structure, in order to realize the data synchronization of each master-slave node in the system, a separate synchronization thread is usually allocated for each master-slave relationship that has been established. The master node in each master-slave synchronization relationship passes the corresponding The synchronization thread sequentially sends synchronization data to the slave nodes, thereby realizing data synchronization between the...
